CL-PD6710/’22
ISA–to–PC-Card Host Adapters
For the CL-PD6712, two pin names are different
than the CL-PD6710 to reflect new functionality:
Document Revision History
Version 3.1
5V_DET became VS1#/A_GPSTB
Following are major changes between September 1995
and May 1997 versions of this data sheet:
N.C./RESERVED became VS2#/B_GPSTB
For the CL-PD672X, two pin names were
changed to reflect new functionality:
General
The CL-PD6710 replaces the CL-PD6712, which was
taken out of production.This change is reflected through-
out this data sheet. Major differences of the CL-PD6710
from the CL-PD6712 include:
A_5V_DET became A_GPSTB
B_5V_DET became B_GPSTB
For the CL-PD67XX, four pin names were
changed to reflect their full functionality:
The CL-PD6710 does not support DMA.
Only a single voltage sense pin is available.
GPSTB functionality is not supported.
IRQ12 became IRQ12/LED_OUT*
IRQ15 became IRQ15/RI_OUT*
BVD1/-STSCHG became BVD1/-STSCHG/-RI
BVD2/-SPKR became BVD2/-SPKR/-LED
References to the CL-PD6720 were removed. Refer-
ences to the CL-PD672X were replaced with
CL-PD6722.
For the CL-PD67XX, two pin names were changed
to match other Cirrus Logic PC Card products:
For the CL-PD6710, two pin names were changed from
the CL-PD6712 to reflect their different functionality:
SLOT_VCC became SOCKET_VCC
VDD became CORE_VDD
VS1#/A_GPSTB is now 5V_DET.
VS2#/B_GPSTB is now a no connect.

2.2 I/O type codes changed.
2.2 The General-Purpose Strobe/Voltage Sense pins
in the CL-PD6712 (VS1#/A_GPSTB and
VS2#/B_GPSTB) were replaced by the 5V_DET
in the CL-PD6710.
2.3 Table columns rearranged, power control pins
placed in their own table.
Table added for general-purpose strobe / voltage
sense pins.
5.1 The Extended Index and Extended Data registers
(Scratchpad, Data Mask 0, Data Mask 1, Exten-
sion Control 1, Maximum DMA Acknowledge
Delay, Reserved, External Data, and Extension
Control 2) are only available on the CL-PD6722,
not on the CL-PD6710.
3.1.2 Windowing figures added.
3.1.3 Functional block figure added.
3.1.5 More information about LED_OUT*, RI_OUT*,
DACK*, and DRQ alternate functions of interrupt
pins added.
3.1.6 Section on general-purpose strobe added.
3.1.7 Section on voltage sense added.
